Check out our full coverage and the latest tweets from CNN correspondents on the ground.

[Update 6:22 a.m. Friday in Cairo, 11:22 p.m. Thursday ET] More large anti-government protests are expected Friday in Cairo, Alexandria and elsewhere in Egypt, despite Mubarak's announcement late Thursday that he'd delegate his powers to Vice President Omar Suleiman.

[Update 6:20 a.m. Friday in Cairo, 11:20 p.m. Thursday ET] U.N. Secretary-General Ban Ki-moon said in a statement late Thursday that the United Nations "stands ready to assist" in the process of ensuring "genuine and inclusive dialogue with all stakeholders" in order to expedite a "transparent, orderly and peaceful transition that meets the legitimate aspirations of the Egyptian people."

[Update 4:29 a.m. in Cairo, 9:29 p.m. ET] - Following Mubarak's Thursday night speech, thousands of demonstrators in Cairo's Tahrir Square have been showing their defiance to his rule by lying down on the streets and sidewalks under blankets for a massive "sleep in." On one wide sidewalk, about a hundred protesters lay next to each other under blankets.

Update 3:00 a.m. in Cairo, 8:00 p.m. ET] U.S. President Barack Obama urged the Egyptian government "to move swiftly to explain the changes that have been made, and to spell out in clear and unambiguous language" the process that will lead to democracy.

"The Egyptian people have been told that there was a transition of authority, but it is not yet clear that this transition is immediate, meaningful or sufficient. Too many Egyptians remain unconvinced that the government is serious about a genuine transition to democracy, and it is the responsibility of the government to speak clearly to the Egyptian people and the world," he said in a statement. "The Egyptian government must put forward a credible, concrete and unequivocal path toward genuine democracy, and they have not yet seized that opportunity."

Obama did not call on Mubarak to step down, but he did call for emergency law to be lifted while negotiations continue among the government, opposition parties and civil society on the country's future.

"As we have said from the beginning of this unrest, the future of Egypt will be determined by the Egyptian people. But the United States has also been clear that we stand for a set of core principles. We believe that the universal rights of the Egyptian people must be respected, and their aspirations must be met. We believe that this transition must immediately demonstrate irreversible political change, and a negotiated path to democracy."

[Update 2:10 a.m. in Cairo, 7:10 p.m. ET] Disappointed. Angry. Frustrated. These are some of the words being used by CNN correspondents to describe the mood among protesters after President Mubarak's speech that designated Vice President Omar Suleiman the de-facto president of Egypt.

"He's playing the same old game. He hasn't done anything new," a protester told CNN's Fred Pleitgen. "Suleiman is the same as Mubarak. And we will keep coming out here each day until he's gone."

Read here for more crowd reaction, plus a roundup of expert opinion and reaction to the speeches, with a look at where the Egypt story goes from here.

[Update 1:56 a.m. in Cairo, 6:56 p.m. ET] An estimated crowd of 1,000 protesters are closing in on Egypt's presidential palace, where a heavy security presence is guarding the palace and several government buildings nearby.

[Update 1:29 a.m. in Cairo, 6:29 p.m. ET] But what about CIA Director Leon Panetta's statement to Congress earlier today that there is a "strong likelihood" that Mubarak might step down?

A U.S. intelligence official tells CNN’s Pam Benson that Panetta was referring to press reports.

"This is not an intelligence failure. The intelligence community has been tracking events in real time, and actions and decisions change in real time," the official said.

During the House Intelligence committee hearing this morning, Panetta responded to a question with this headline-making statement: "As you can see I got the same information you did, which is there is a strong likelihood that Mubarak may step down this evening, which would be significant in terms of where the hopefully orderly transition in Egypt takes place."

But about 45 minutes later in the hearing he walked it back when he said, "let me say, just to make very clear here, I received reports that possibly Mubarak might do that, we are continuing to monitor the situation, we have not gotten specific word that he would do that."

[Update 1:08 a.m. in Cairo, 6:08 p.m. ET] Tweet from Egyptian opposition figure Mohamed ElBaradei: Egypt will explode. Army must save the country now.

In an interview with CNN's Wolf Blitzer, ElBaradei said it's unclear whose side the Army is on. As for Suleiman taking control of the presidency?

"Suleiman is an extension of Mubarak. They are twins," he said. "For the sake of their country, they should go."

[Update 1:00 a.m. in Cairo, 6:00 p.m. ET] Parliamentary speaker Ahmed Fathi Srour tells Nile TV that President Hosni Mubarak's move puts the authority for the day-to-day running of the government in Vice President Omar Suleiman's hands. That would include oversight of the police, the Interior Ministry and other key agencies, control of economic policy and running any negotiations with the opposition.

Srour echoed Mubarak's statement in adding that the constitution specifically prohibits the president from delegating other key powers to the vice president. As a result, power to dismiss parliament or dismiss the government and the power to ask for amendments to the constitution remain in Mubarak's hands, not Suleiman's.

[Update 12:40 a.m. in Cairo, 5:40 p.m. ET] President Hosni Mubarak has transfered all effective powers of the presidency to Vice President Omar Suleiman, making Suleiman the de-facto president of Egypt, the Egyptian Ambassador to the United States said.

"The president did indicate very clearly he was transferring all his presidential authority to the vice president," Sameh Shoukry told CNN's Wolf Blitzer. "President Mubarak has transferred the powers of the presidency to his vice president, who will now undertake all authority as president."

That makes Mubarak the de jure head of state, or as a matter of law, and Suleiman, the de-facto head of state and the military, Shoukry said, attributing the information to the Egyptian government. Suleiman has no power to dissolve parliament or to make amendments to the constitution, he said.

[Update 12:25 a.m. in Cairo, 5:25 p.m. ET] CNN's Ivan Watson says you need only look at the network of tents and a makeshift wooden shelter erected in the middle of Tahrir Square for evidence of what people are planning to do next: "These people are not going. 'When he leaves, we leave.' This is just the beginning."

[Update 12:15 a.m. in Cairo, 5:15 p.m. ET] Israeli Defense Minister Ehud Barak offered his view on the situation in Egypt Thursday during a visit to the United Nations:

"I think we should not pretend that we are more important for the Egyptian people than their own interests... it's up to the Egyptian people to find their way and to do it according to their own constitution, norms and practices."

[Update 11:58 p.m. in Cairo, 4:58 p.m. ET] Protesters are forming a human chain around the offices of the state-run television after Mubarak's announcement that he will stay in power until September. "The anger is deep, it's profound and widespread," CNN's Ben Wedeman reports of the crowd reaction. Some speculate that the government is trying to provoke strong reaction to justify a crackdown.

[Update 11:38 p.m. in Cairo, 4:38 p.m. ET] Vice President Omar Suleiman says President Hosni Mubarak's speech affirms his commitment to responding to "the demands of the people" and to making the "safety, security and stability" of Egypt a priority above any other consideration.

He also commended the "youth revolution" while urging young people to "go back to your houses, go back to your work, the homeland needs your work." He also told them to ignore the "satellite images" that "mar Egypt" by fomenting revolt.

[Update 11:35 p.m. in Cairo, 4:35 p.m. ET] A recap of the highlights of President Hosni Mubarak's speech:

[Update 11:00 p.m. in Cairo, 4:00 p.m. ET] The crowd in Tahrir Square erupts into roars of "get out" as Mubarak announces he will not step down.

"I will not submit to any international pressures," he says, according to an unofficial translation. "I have preserved my dignity and preserved the peace for Egypt and I have worked hard for the renaissance, I have never tried to have more authority, and I think the majority of people know very well who Hosni Mubarak is, and it hurts my heart when I see and hear from my own colleagues and my own people, but I –I know the juntion that we are facing right now, but I am fully convinced that Egypt will pass these difficult times."

[Update 10:45 p.m. in Cairo, 3:45 p.m. ET] "I will respond to your demands and your voices and this is a commitment that cannot be reversed. I am committed to carrying out my promises in all credibility," President Hosni Mubarak says in a televised address, according to an unofficial translation.

[Update 10:25 p.m. in Cairo, 3:25 p.m. ET] Change is in the air and on the airwaves, CNN's Ben Wedeman tweets: "Egypt State TV now reading long list of charges against former NDP business tycoon Ahmed Ezz, Gamal Mubarak's ex-best friend. Unbelievable."

The U.S. military does not work with governments that come to power by military coup, and while there is talk Egypt will be led by some type of military consensus arrangement, this still poses challenges for the Pentagon, the official said.

[Update 8:31 p.m. in Cairo, 1:31 p.m. ET] State TV is running a promo showing protesters shaking hands with the military, saying "Egypt is Changing." Such a favorable depiction of protesters is unprecedented, CNN's Tom Fenton says.
